  • Calculate KS Statistic with Python

    It stands for Kolmogorov–Smirnov which is named after Andrey Kolmogorov and Nikolai Smirnov. It compares the two cumulative distributions and returns the maximum difference between them. It is a non-parametric test which means you don't need to test any assumption related to the distribution of data. In KS Test, Null hypothesis states null both cumulative distributions are similar. Rejecting the null hypothesis means cumulative distributions are different.
    In data science, it compares the cumulative distribution of events and non-events and KS is where there is a maximum difference between the two distributions. In simple words, it helps us to understand how well our predictive model is able to discriminate between events and non-events.

  • Python binding for Kuesa

    KUESA™ is a Qt module designed to load, render and manipulate glTF 2.0 models in applications using Qt 3D.

    Kuesa provides a C++ and a QML API which makes it easy to do things like triggering animations contained in the glTF files, finding camera details defined by the designer, etc.

    It is a great tool so that designers and developers can share glTF based 3D assets.

    With the upcoming release of Kuesa 1.1, we are introducing a python binding for Kuesa. This provides a simple yet powerful way for programmers to integrate glTF content in their python applications with just a few lines of code.

  • Mike Driscoll: PyDev of the Week: Cris Medina

    I was born in the Dominican Republic. I finished highschool there and went to Puerto Rico to study Computer Engineering, specializing in hardware. But I’ve been writing software in some form since I can remember. My dad introduced me to IBM System 360 Basic as my first language. Go figure!

    Most of my professional career (going on 17 years now) was spent doing test engineering, along with developing all the hardware and software tools required to execute those tests and maintain their infrastructure. The rest of the time I’ve held formal software engineering roles.

    I like to spend some of my free time with music. My mother is a music teacher and she got me into piano early on. Though I moved into string instruments as I got older. Today I mostly play classical guitar, but I own several types of guitars and dabble in other string instruments.

  • Backend support merged

    This has been a very exciting week for me, with lots of progress made on my GSoC project. For the past couple of months I've been working on adding the new scipy.fft module which supercedes the existing scipy.fftpack submodule and adds a range of new features and interface improvements. Chief among these planned features was a backend system, allowing users to install their own fft libraries as implementations for the scipy.fft interface.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
